With Q-XibLll'lg i pes of soi-heft fixtures for in vzmd t (Ififii'i'if lumps it is (-us'mnr my 10 suround the eniro ear lamp with :1 metallic r wholly insuhahul irate terminals; the Contact 5701.: fccted nsrafl a with WOH i humps by an exterior and an inflarizw" or sent With six-h ways; a scrowi em if. a e heifer as clearly shown in Fig. 2, the disks being held together at their outer rim in any preferred manner and in the present instance connected, to a further reflecting surface in the nature of a truncated cone, as shown in Fig. l. 3 represents the novel means, in the nature ot'a slotted cylindrical sleeve, for accomplishing the results above referred to. .4 represents the outer metallic casing of an incandescent lamp fixture which is insulated in the usual manner from the outer conducting sleeve of the lamp 7 by an insulating sleeve 5 as is customary, 6 representing the longitudinal slots, as clearly illustrated. In

using this improved device, the reflector or shade is first slipped over the lamp by inserting the former through the central opening, which opening is clearly illustrated in Fig. In effecting this insertion the arms 2, 2, assume the curvilinear position shown in Fig. 1.

In the'use of my novel rcllector or shade as disclosed in the before-mentioned application 1 have ascertained that when the inner ends of the arms 2, 2 are located in place against the screw-threaded portion (3 of the lamp, there is given to the entire reflector or shade an electrical potential which makes the device dangerous, by reason of such po tential, as will be readily understood by those skilled in the art. For overcoming this objection, therefore, I secure the slotted sleeve 3 directly to the lower end of the outer casing 4 by forcing it over the end thereof in the manner clearly illustrated in Fig. 1, so that this sleeve becomes in effect a permanent part of the fixture; I then secure the lamp in place with the reflector or shade attached, as before described, and the lamp is finally secured in the usual manner by screwing it home, so that circuit is effected through the tihnnent therein, the lower or curvilinear portion of the sleeve 3 forcing.

the reflector or shade l downward by reason of the frictional contact of said sleeve with the upper ends of the arms 2, 2. It will be apparent, therefore, that by no possibility can there. be any electrical contact between the reflector or shade and either of the conducting terminals of the lamp, by reason of the fact that the metallic arms 2 are wholly sustained by the. glass bulb of the lamp and are held thus sustaincd'by the sleeve 3 which, as before stated, is insulated from the lamp by the sleeve It will also be obviousithat by the provision of such a sleeve 1 am enabled to force the reflector or shade downward much farther than was possible with my reflector or shade as before disclosed,the extent to which such downward location is eliec'ted being limited only by the lengthot the sleeve and the internal diameter of the lower end thereof. By doing this, I am enabled to bring the body portion of the shade downand around the body portion of the light giving filament within the lamp 7.

I make no claim 1n the present application to the subject matter of the reflector or sh de per 50, as shown in the accompanying drawings and hereinbefore described, nor to the same as combined with an electric lamp, as show '1, these features constituting the subject matter of the before-mentioned application.

Having thus described my invention what I claim and desire to secure by Letters latcut of the. linited States is 1. Means for etl'ccting the insulation of a conducting or metallic rellcctor or shade from both of the conducting terminals of an electric. lamp, consisting of a rigid cyliin drical sleeve slotted at one end and curved outwardly at the other, the internal diameter of said sleeve at its slotted end being such as to adapt it to be detacbably secured to the lower-end of the outer casing! of an incandescent electric lamp socket, and of such internal diameter atthe other end that when the lamp is in position in the socket the curved-out portion tits su-lliciently near therearoundto adapt it to frictionally hold the reflector against the lamp, substantially as described. i

Means for tri .-tionally holding a retlector against the outer face of an incandescent electric lamp bulb, consisting of a cylindrical sleeve providtal at one end with means for detachably securing it directly to the outer casing of the socket, the other end being-curved outwarilly so as to correspond in conformation or shlipe with the curvature of the body of the lamp and the supporting Aiamp 5*iure; form incandersent I 6" Alana fixture fol incnndescexri elev- 26 trim lamp using two a, "min-n13 inauated lamp pz'o'vided with two ts rmimmls in am a and :2 was wrzo 1 and sun'mmded by mg suhz' feci 0%: U. \tef). :2 met; insulated from both; an
